3-D printed vessel made from living cells implanted in an animal to test feasibility of using such structures clinically. Blood vessels are a stepping stone to the creation of more complex 3-D printed organs made from biomaterials. Image from the South Carolina Project for Organ Biofabrication.

This image combines pre- and post-treatment scans from the same patient. Analysis of the two scans revealed that the area and size of post-treatment bleeding corresponded to blood-brain barrier disruption (shown in green, yellow and red) prior to therapy. Image courtesy of Richard Leigh, NINDS.

The Tele-Robotic Ultrasound for Distance Imaging (TRUDI) system uses a robotic arm so a remote sonographer can control the echo probe without the need for them to be in the same room or even be in the hospital during an exam or procedure.
